FEED DEVICE FOR DRILLING-RIGS.

1,ooa,o11.

To all whom it may concern:

Be it known that I, Louis E. SHoUP, citizen of the United States,residing at Franklin, in the county of Venango and State ofPennsylvania, have invented certain new and useful. Improvements in FeedDevices for Drilling-Rigs, of which the following is a specification.

The object, construction and operation of my improved feed device fordrilling rigs, are herein set forth with sufficient clearness to enablethose skilled in the art to which it appertains, to make and use thesame.

The object of my invention is to provide a feed device for the tools ofa well drilling rig, such as are used for drilling deep wells, and moreespecially Artesian and oil wells. The device now commonly employed forthis purpose, is what is known as a temper screw and all drillers arefamiliar with the construction and operation of this device. It is,moreover, a well known fact that the temper screw, especially when usedin connection with heavy tools, is very difficult to operate and adjust,its use involving much hard manual labor. It is located quite high up,out of the reach of the driller when standing on the derrick floor, andit is necessary for him to climb upon some support, as a bench or aladder to reach it, and when in reach the labor of operating it isarduous.

The particular object of my invention, therefore, is to provide a feeddevice for drilling rigs which will be easy of access, easy to operate,and which may be easily adjusted in either direction,-upward ordownward. T accomplish said object by means of the construction shown inthe drawings the various figures of which are as follows:

Figure 1 is a side elevation of my improved feed device. Fig. 2 is afront elevation of same. Fig. 3 is a side elevation of a portion of adrilling rig, showing my feed device attached thereto. Fig. 4 is a frontview of the tackle to which the drilling cable is directly attached.Fig. 5 is a plan view of the walking-beam, with portions broken away,and showing the arrangement of pivotal and terminal pulleys thereon.

As will be readily seen by an inspection of Figs. 1 and 2, my deviceconsists of a drum 1, mounted in a framework or bracket 2, which bracketis arranged to be attached to the samson-post 3 or an equivalent portionSpecification of Letters Patent. Patented Sept. 12, 1911.

of a drilling rig. A shaft 4: passes through drum 1, in which it isrigidly inserted, so that the drum and shaft'revolve together. Therespective ends of said shaft pass revolubly through the boxes 5, 5, ofthe bracket 2. A wormwheel 6 is rigidly attached to one end of shaft 4.Below wheel 6 and meshing therewith is a worm 7 which is arranged torevolve wheel 6. Said worm is rigidly aflixed to shaft 8, which passesrevolubly through the bearings 9, 9. One end of shaft 8 is extended toany desired length, and has a hand-wheel 10 upon the outer erd thereofby means of which the worm, the wheel, and the drum may be revolved.

.l/Vhen the feed device, thus constructed, is placed in operation, it isattached to the samsonpost 3 or an equivalent member of the drillingrig, or it may be attached to any other convenient portion of thedrilling rig. Suitable cables 11, are attached to the drum 1 and fromthence they are passed over the pulleys 12 that are mounted, one oneither side of post 3, upon the gudgeons 13 of saddle 14. From pulleys12, cables 11 are extended outward and pass over the terminal pulleys15, which are affixed to the outer end of the walking-beam 16. Frompulleys 12, the cables 11 extend downward and have attached theretosuitable tackle for the attachment of a drilling cable 17 whichequipment preferably is as follows: eyebolts 18, threaded at their lowerends for the reception of a turn-buckle 19, a stirrupbolt 20, alsothreaded at its upper end for the reception of said turn-buckle 19.- Theloops of said stirrups engage the upper yoke 21. Below yoke 21 andattached thereto is a swivel-yoke 22, so constructed that it is free torevolve horizontally. Cable clamps 23 are attached to yoke 22 by meansof the links 24. Drilling tools are attached to the lower end of cable17 in the usual manner.

The turn-buckles 19 constitute a valuable feature of my invention, as bythese I am enabled to accurately equalize the strain upon each of thecables 11, and without some provision of this sort, such equalization ofstrain would be diflicult to secure.

In the operation of my improved feed, the weight of the drilling toolsis sustained by the cables 11, and said tools are fed downward byrevolving drum 1 by means of the wornrgear, so that said cables are fedout as the necessity of the work requires,that is,

as the drill works its way downward into the rock. Said feed may beregulated as desired, and with much greater ease and facility than witha temper screw.

' My improved feed devicemay be located at any desired height that bestsuits the convenience of the operator. It may be attached to the samsonpost, or to any other convenient part of the rig, or with slightmodification, it may be located upon, or attached to the floor of thederrick. Shaft 8 may be of any desired length, to position thehand-wheel 10 in the most convenient place for the operator. Adjustmentsmay be as readily made with my device when the drill is in operation aswhen it is not operating, and from the position which the operatorusually occupies when heis tending the tools.

While the drawings show a particular construction by means of which myinventive idea may be mechanically embodied, I do not wish to beunderstood as confining myself to the exact construction here shown, asvarious modificationsthereof could be employed without departing fromthe scope V of my invention, the essence of which is the provision of astationary feed. mechanism, of easy access and manipulation, which maybe readily substituted for the temper-screw now commonly used, and whichis so diflicult of access and operation.

WVhat I'claim and desire to secure by Let ters Patent is 1. In a feeddevice for drilling rigs, the combination of a walking beam, a supportfor said beam, a pulley mounted upon each side of said beam at thepivotal support thereof, terminal pulleys mounted upon the outer end ofsaid beam, one upon either side thereof, an'adjusting means, cablesattached at one end to said adjusting means and passing over saidpivotal and said terminal pulleys, means upon the other end of saidcables arranged for the attachment of drilling tools, and means arrangedto equalize the tension upon said cables.

drum mounted upon said support, a worm.-

gear arranged to revolve said drum, feed cables attached to said drumand passing over said terminal and pivotal pulleys, means attached tosaid cables arranged to equalize the tension thereon, and means carriedby said equalizing device for the attachment of a drilling cable.

3. In a feed device for drilling rigs, the combination of awalking-beam, pivotal pulleys attached to said beam at the pivotal pointthereof, terminal pulleys attached to the outer end of said beam, adrilling cable, means for engaging said cable, feed cables attached tosaid engaging means and passing over said terminal and said pivotalpulleys, an adjust-ing means to which said cables are attached for thepurpose set forth, and means for equalizing the tension upon saidcables.

In testimony whereof I atfix my signature in presence of two witnesses.
